Mastering the skills and knowledge to be an expert in HVACR technology is not a quick or easy task, but it can be a rewarding and stable career. According to the U.S. Bureau of Labor Statistics, there are 415,800 heating, air conditioning, and refrigeration mechanics and installers nationwide and Michigan employs 7,410 of them. Employment is projected to grow 6 percent from 2022 to 2032 throughout the country, adding more than 20,000 of these skilled workers to the ranks. According to CareerOneStop, the U.S. Department of Labor’s job search website, that growth rate is expected to be higher in Michigan at 9%.

That statistic is supported by how many contractors are trying to find skilled tradesmen. According to the Associated General Contractors of America, 2020 AGC-Autodesk Workforce Survey, 60% of firms in the U.S. and a whopping 88% of firms in Michigan had unfilled hourly craft positions like plumbers, electricians, and HVAC technicians. So, if you get the training you need, you will have a lot of jobs to choose from when you’re ready.

A large part of what HVAC contractors and technicians do is replace and repair existing systems. And, as more of an emphasis is placed on energy efficiency and reducing pollution, systems need to be retrofitted, upgraded or replaced entirely to comply with these new standards. Licensing requirements for HVAC contractors vary from state to state and in some cases, from locality to locality. Michigan is fairly uniform statewide, but in some parts of the state, you may have to be registered locally as well.

Licensing Requirements for HVAC Contractors in Michigan

Is a license required to work as an HVAC professional in Michigan? Yes.

To legally perform heating, air conditioning, and refrigeration work in the state of Michigan, you must be licensed or a technician apprentice working under someone who is licensed. Mechanical Contractor licenses are issued through the Michigan Department of Licensing and Regulatory Affairs (LARA). The Bureau of Construction Codes, Mechanical Division licenses Mechanical Contractors in a variety of different classifications and specialties. 

The state does not license technicians, but does require a special license for repairing or installing boilers. In 2017, the Skilled Trades Regulation Act became law and consolidated regulations for five skilled trade industries including mechanical or HVAC/R to create one uniform code that streamlined and made the application, testing, and renewal processes for these skilled trades consistent. Some of Michigan’s cities still retain the authority to require state-licensed tradesmen to register with their own governing agencies, so you always want to check with the jurisdiction where you intend to work to make sure you’re following any local requirements.

Michigan HVAC Licensing Exam Details

The examination is administered by PSI testing services. To prepare PSI suggests:

  • Start with a current copy of the Candidate Information Bulletin and use the examination content outline as the basis of your study.

  • Read/study materials that cover all the topics in the content outline including the Michigan Mechanical Code and take practice tests.

  • Take notes on what you study. Putting information in writing helps you commit it to memory and it is also an excellent business practice. Discuss new terms or concepts as frequently as you can with colleagues. This will test your understanding and reinforce ideas.

  • Your studies will be most effective if you study frequently, for periods of about 45 to 60 minutes. Concentration tends to wander when you study for longer periods of time.

Each of the 14 exams is described in detail including the number of questions and the time limit to complete it. The Bulletin will also specify which reference materials you may use and what items are not allowed in the testing center. There are seven PSI testing centers in Michigan and they are located in Dearborn, Holt, two in Southfield, Grand Rapids, Gaylord, and Marquette.

LARA also provides a reference list on its website of materials that can help you prepare for each of the various exams.

Michigan does not have any specific reciprocity agreements with any other states; however, legislation has been introduced that will make current military personnel, veterans, and their dependents eligible for license reciprocity in Michigan. “Servicemembers will be eligible if they hold a valid occupational license in another state, are in good standing with no pending disciplinary action, and demonstrate competency in their profession through education, training and/or work experience. The Department of Licensing and Regulatory Affairs (LARA) will determine whether these criteria are satisfied.”

HVAC Specific Requirements: EPA Certification

Everywhere throughout the country, including Michigan, federal-level EPA regulations under Section 608 of the Clean Air Act require that technicians who maintain, service, repair, or dispose of equipment that could release refrigerants into the atmosphere must be certified. EPA Section 608 HVAC Certification is required for any professional who conducts refrigerant line-pressure tests or handles or adds refrigerant to existing air conditioning systems.

Most training programs can direct you to how and where to get that certification, or your employer will require you to get it before handling refrigerant. You can also go to and key in 608 Certification in the search bar to find out which institutions in your state offer certification programs.

Take Certification Exam: You must acquire your EPA Certification from an approved organization. A list of these organizations can be found on the EPA’s website. There are four types of EPA Certifications for Refrigerant. They allow for different levels of certification for different scopes of work.

  • Type I – for servicing small appliances containing five pounds of refrigerant or less.

  • Type II – for servicing high-pressure units that contain five pounds or more of refrigerant (including most small commercial and residential systems).

  • Type III – for servicing or disposing of low-pressure appliances.

  • Universal – for servicing all systems and appliances covered under Types I, II, and III. Generally more useful than targeting any one specific certification.

Core Exam

For all certifications, you must pass the “Core Section” of the EPA certification exam. It covers the following topics:

  • Ozone depletion

  • Clean Air Act and the Montreal Protocol

  • Section 608 regulations

  • Substitute refrigerants and oils

  • Refrigeration

  • The Three R’s (Recover, Recycle, Reclaim)

  • Recovery techniques

  • Dehydration evacuation

  • Safety

  • Shipping

National HVAC Certifications

Other certifications can help you demonstrate your proficiency to potential employers and clients. North American Technical Excellence (NATE) certification, ASHRAE (American Society of Heating, Refrigeration and Air-Conditioning Engineers) certification, and other professional certifications are not required but can add to your marketability as a service provider and therefore increase your opportunity to make more money.

Continuing Education/Renewal

There is currently no continuing education requirement to renew your Michigan Mechanical Contractor license. Mechanical contractor licenses expire every three years. You should receive notice at least 60 days before expiration with renewal instructions and the fee required.
